Answer 1

Use

implementation 'com.android.support:appcompat-v7:27.1.1'

Don't use like

implementation 'com.android.support:appcompat-v7:27.+'

It may give you an error and don't use an older version than this.

or event don't do like this

implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1' 

etc... numbers of libraries and then

implementation 'com.android.support:appcompat-v7:27.+'

the same library but it has a different version, it can give you an error.

Answer 2

I downgrade the support

previously it was
implementation 'com.android.support:appcompat-v7:27.0.2'

Use it

implementation 'com.android.support:appcompat-v7:27.1.0'

implementation 'com.android.support:design:27.1.0'

Its Working Happy Codng

Answer 3

It might be cause of a library, I faced it because of Glide.

It was

implementation 'com.github.bumptech.glide:glide:4.7.1'

So I added exclude group: "com.android.support" And it becomes

implementation ('com.github.bumptech.glide:glide:4.7.1') {
        exclude group: "com.android.support"
    }

Answer 4

I know it's a late answer but I had the same problem and my solution was just adding implementation 'com.android.support:design:28.0.0 or any above support design libraries !!
